Returning to the description of FIG. 1 again, although not shown, the VTR 100 includes a magnetic tape as a medium for recording a signal, a magnetic head for recording a signal on the magnetic tape, a rotating drum attached with the magnetic head, and a magnetic tape. There is a mechanism such as a capstan to drive.

  Next, components of the IRD 200 and the TV 250 will be described.

201 is an input terminal for inputting a digital broadcast signal, and 202 is a digital broadcast receiving tuner for demodulating the input digital broadcast signal. A decoder 203 converts the digital signal received by the digital broadcast receiving tuner 202 into an analog video and audio signal and outputs the analog video and audio signal. In addition, the decoder 203 has a function of displaying information by making the video signal to be output a superimpose display or a blue back display. In this embodiment, the function of displaying the information of the decoder 203 is used to display a setting screen and a reservation confirmation screen in a blue background. Reference numeral 204 denotes an output terminal for outputting the converted analog video and audio signals, and the video and audio signals output therefrom are supplied to the input terminal 10 of the VTR 100. An IRD system control circuit 220 controls the entire operation of the IRD 200, and controls all the components of the IRD 200 described above. Also, the IRD system control circuit 220 inputs the digital information signal received by the digital broadcast receiving tuner 202, from which the program name of the broadcast program, called program arrangement information,
Information including broadcast date and time, contents, and the like can be extracted to create a program guide screen that lists the contents of programs that will be broadcast in the near future, and can be output as a video signal screen by the decoder 203. A receiving unit 262 of the remote controller transmits a user operation request from the remote controller to the IRD system control circuit 220.

FIG. 3 is a block diagram showing the internal structure of the decoder. The expansion circuit 2031 expands the compressed digital signal, and the digital on-screen display circuit (digital on-screen display circuit) digitally multiplexes information on the video portion of the digital signal. (Hereinafter referred to as a digital OSD circuit) 2032 and an encoder 2033 for converting a digital signal into an analog video and audio signal. The digital OSD circuit 2032 performs the actual display of the superimpose display and the blue back display.

Returning to the description of FIG. 1 again, reference numeral 251 denotes an input terminal for inputting video and audio for the TV 250, and inputs video and audio signals supplied from the output terminal 16 of the VTR 100. A monitor screen 252 displays the input video signal.

VTR 100 and IRD 200 are connected by communication line 270, and 271 and 272 are connection terminals of communication line 270.

When the contents of communication used in this embodiment are divided into subject: verb: main object: target object: subject, the subject indicates a source device, the target indicates a specific operation state or setting content of the receiver, The verb indicates setting or acquisition of a value for the data indicated by the object, and the target complement indicates the contents to be set when the verb is set.

For example, in order for the IRD 200 to put the VTR 100 in the recording state, the subject = IRD, the verb = setting, the main subject = the running state of the VTR, and the target complement = recording. With such a function of setting the other party's state, the VTR 100 can perform operations such as switching the power on / off of the IRD 200 and changing the channel, and the IRD 200 can switch the running state of the VTR 100 to recording, stopping, playing, etc. Therefore, it becomes possible to turn on the power of the VTR 100 and the IRD 200 in conjunction with each other.

When the VTR 100 listens to the IRD 200 for the channel number being received, subject = VTR,
The channel number of the tuner with verb = acquire, subject object = IRD. With such a function of acquiring the other party's state, the VTR 100 can monitor the operation state of the IRD 200 and detect the change. Therefore, when the operation state changes, the analog OSD circuit 15 causes the IRD 200 to change.
It is possible to display the latest status of the text as characters or diagrams. In this embodiment, a screen such as a status display screen for notifying the user of information by superimpose display is displayed on the analog OSD circuit 15 controlled by the VTR system control circuit 20 including the operation status of the IRD 200.

Furthermore, this protocol has means for knowing the type and name of the main object that the partner device has, and the type and name of the target complement that can be set in the main object.
With this function, the IRD 200 can acquire the type and name of the setting item of the VTR 100 and the type and name of the option for the setting item, and the digital OSD circuit 2032 can display the setting screen for the VTR 100. In this embodiment, screens such as a setting screen and a reservation screen for notifying the user of information by blue background display are displayed on the digital OSD circuit 2032 controlled by the IRD system control circuit 220, including information on the VTR 100.

  The reason for sharing information display in this way is as follows.

Since the digital OSD circuit 2032 has a function of displaying a screen for a program guide for digital broadcasting, the screen resolution is higher than that of the analog OSD circuit 15, and the number of colors is high. However, characters cannot be displayed against the background of the video output from the analog broadcast receiving tuner 12 or the video reproduced by the magnetic head. For this reason, in this embodiment, the superimpose display is shared by the analog OSD circuit 15 and the blue back display is displayed by the digital OSD circuit 2032.

The actual communication between the VTR 100 and the IRD 200 is performed between the VTR system control circuit 20 and the IRD.
This is performed between the system control circuits 220. Further, when the VTR 100 and the IRD 200 can normally communicate, the VTR system control circuit 20 receives all user operation requests transmitted from the remote controller 260, and the IRD system control circuit 220 interrupts the receiving operation.

The operation of this recording / reproducing apparatus will be described when various buttons on the remote controller 260 are pressed.

When the power button 300 of the remote control 260 is pressed, the VTR system control circuit 20 turns on the power of the VTR 100 and transmits a power-on request to the IRD 200. The IRD system control circuit 220 receives this request and receives the IRD 200. Turn on the power. As a result, VTR100
And the power state of the IRD 200 are turned on and off in conjunction with each other.

At this time, if the contact of the input change-over switch 13 is connected to the A side, the input terminal 11
The analog broadcast signal input to R100 is converted into video and audio by the analog broadcast receiving tuner 12, and is output from the output terminal 16 via the input selector switch 13, the signal processing circuit 14, and the analog OSD circuit 14 (video signal only), The program received by the analog broadcast receiving tuner can be viewed on the TV 250. If the contact of the input changeover switch 13 is connected to the D side, the digital broadcast signal input from the input terminal 201 to the IRD 200 is converted into a digital information signal by the digital broadcast reception tuner 202, and an analog video and video signal are converted by the decoder 203. It is converted into an audio signal and output from the output terminal 204. Furthermore, these signals are input from the input terminal 10 to the VTR 100, and output terminals via the input selector switch 13, the signal processing circuit 14, and the analog OSD circuit 15 (video signal only).
16 is a digital broadcast program that can be viewed on the TV250.

When the status display button 309 of the remote controller 260 is pressed, the VTR system control circuit 20 performs the following processing according to the connection destination of the input selector switch 13.

When the contact of the input changeover switch 13 is connected to the A side, the VTR system control circuit 20 analogizes the operation mode of the VTR 100 such as “stop, record, playback” and the information of the reception channel of the analog broadcast reception tuner 12 The information is transmitted to the OSD circuit 15, and the analog OSD circuit 15 is instructed to multiplex these pieces of information into the video signal.

Next, when the contact of the input changeover switch 13 is connected to the D side, the VTR system control circuit 20 acquires the channel number received by the digital broadcast receiving tuner 202 from the IRD 200, and the operation mode of the VTR. The information of the received channel of digital broadcasting is displayed by the analog OSD circuit 15.

When the channel up button 302 of the remote control 260 is pressed, the VTR system control circuit 20 performs the following processing according to the connection destination of the input selector switch 13.

When the contact of the input changeover switch 13 is connected to the A side, the VTR system control circuit 20 searches for the channel number of the next analog broadcast to be selected, and tunes the analog broadcast reception tuner 12 to the searched channel. At the same time, a request for display of the channel number is issued to the analog OSD circuit 15, and the selected analog broadcast video and its channel number are displayed on the monitor screen 252. The operation of the VTR 100 at this time is the same as the operation of the conventional VTR.

Next, when the contact of the input changeover switch 13 is connected to the D side, the VTR system control circuit 20 transmits a channel up request to the IRD 200. The IRD system control circuit 210 receives it, searches for the channel number of the next digital broadcast to be selected, and controls the tuning of the digital broadcast reception tuner 202 to the searched channel. VTR system control circuit 2
0 detects that the reception channel of the IRD 200 has been changed, and issues a request to display the channel number to the analog OSD circuit 13, and the selected digital broadcast video and its channel number are displayed on the monitor screen 252. The

The above operation is an example of a channel selection method in which the type of broadcast signal is selected by the input selector switch 13 and then a predetermined channel is selected by the channel up button or the channel down button. It is conceivable to use a button to circulate in a loop including analog broadcasting and digital broadcasting, or directly select a predetermined channel of a predetermined broadcast using a numeric button, but communication performed between the VTR 100 and the IRD 200 at this time The contents of the control can be easily guessed and will not be described in particular.

When the setting screen button 307 of the remote control 260 is pressed, the setting screen is displayed on the decoder 203 of the IRD 200.
Therefore, the VTR system control circuit 20 transmits a setting screen display request to the IRD 200.
The IRD system control circuit 220 receives this and creates the data for the setting screen, and the decoder 203
A display request. Further, the VTR system control circuit 20 detects that the IRD 200 has displayed the setting screen, and connects the video input selector switch 13V to the contact D side. As a result, IRD2
The setting screen output from 00 is input to the VTR 100 from the input terminal 10V, supplied to the input terminal of the TV 250 via the video input selector switch 13V, the video signal processing circuit 14V, the analog OSD circuit 15, and the output terminal 16V. A setting screen is displayed on the screen 252.

FIG. 4 shows an example of a setting screen displayed by the IRD 200. The screen 400 is an example of a selection screen for selecting various setting screens. Here, the hatched portion 401 indicates the current cursor position.

When the IRD 200 is displaying the setting screen, when the VTR system control circuit 20 accepts a request for a button to be used on the setting screen, the content is unconditionally transmitted to the IRD 200, and the IRD system control circuit 220 receives it. Switch the setting screen according to the contents, or change the contents of the setting items. Here, the buttons used on the setting screen are a cursor button 310 for selecting a setting item in the setting screen, a decision button 311 for determining an option, and a number button 300 for inputting a number.

When the enter button 311 is pressed while the cursor is on the “video mode setting” on the screen 400,
The IRD system control circuit 220 obtains from the VTR 100 the types and names of the setting items held by the VTR 100, their choices and their names, and the current setting contents, creates a setting screen for the VTR, and sets the video mode to the decoder 203. Display the setting screen.

A screen 410 shows an example of a video mode setting screen displayed by the IRD 200. Here, 411 indicates the current cursor position, and 412, 413, and 414 indicate items that are currently selected. The user moves the cursor to the choice of the item whose setting is to be changed and presses the OK button 311 to change the setting contents. However, when the OK button 311 is pressed on the screen 410, the “playback CM skip” mode is changed from “ON” to “OFF”. ”.

When the content of the setting item is changed, the IRD system control circuit 220 transmits the content of the changed item to the VTR 100, and the VTR system control circuit 20 receives this and rewrites the internal state data.

If the OK button 311 is pressed while the cursor is on “END” on the setting screen, the IRD
The system control circuit 220 detects this and ends the display of the setting screen.
The VTR system control circuit 20 detects the end of the display of the setting screen, returns the operation request processing of the remote control 260 to the normal operation, and returns the video input selector switch 13V to the state before the menu screen display.

Here, when the IRD 200 is displaying the setting screen, the VTR system control circuit 20
The status display request from the remote control 260 is ignored. If the setting screen is displayed during the status display, the status display is terminated. This is because the IRD200 displays a blue screen and V
This is to prevent the TR100 from displaying a state display screen that is superimposed.

Further, the VTR system control circuit 20 ignores the setting screen display request from the remote controller 260 during recording. This is to prevent the video signal to be recorded from entering the setting screen.

When the program guide button 306 of the remote control 260 is pressed, the VTR system control circuit 20 causes the IRD 200
The IRD system control circuit 220 receives the request and displays the program guide information of the broadcast program from the program arrangement information included in the digital information signal received by the digital broadcast reception tuner 202, etc. Information is extracted and a program guide listing the contents of programs to be broadcast in the near future is created. Further, the IRD system control circuit 220 acquires the channel number registered in the VTR 100 and converts the channel number of the analog broadcast into a form including the program guide screen.

FIG. 5 is a diagram showing an example of a program guide screen displayed in the present embodiment. Channel number is 1
The programs of 00 or more are digital broadcast programs, and the program title and broadcast time acquired from the program arrangement information are shown. A program having a channel number less than 100 is an analog broadcast program, and is composed of blocks divided in units of 15 minutes for each channel.

When reserving a digital broadcast program, move the cursor to the desired program and select the button
Decide in 311. When the desired program is determined, the IRD system control circuit 220 extracts the channel number, start time, and end time of the designated program as reservation information and transmits it to the VTR 200. The VTR system control circuit 20 receives it and stores it as reservation information.

When reserving an analog broadcast program, several 15-minute blocks are selected for each desired channel, and the start time and end time are determined in 15-minute units. First, select and decide the block corresponding to the start time of the desired channel, and then select and decide the block corresponding to the end time of the same channel, so that all the blocks included between the two blocks Is selected. The screen 500 shows a screen when 8 channels of analog broadcasting are reserved at 17:15 to 18:15 on Thursday, 27th. The IRD system control circuit 220 extracts the channel number, start time, and end time from the selected blocks as reservation information and transmits it to the VTR 100. The VTR system control circuit 20 receives it and stores it as reservation information.

When the reservation confirmation button 308 of the remote controller 260 is pressed, the VTR 100 and the IRD 200 perform the same communication and operation as in the setting screen display described above. However, in order to generate the reservation confirmation screen, the IRD system control circuit 220 transmits a request for acquiring the contents of the reservation stored in the VTR 100 to the VTR 100, and receives the reply to create the reservation confirmation screen. The operation is added.

When the reservation content is deleted on the reservation confirmation screen, the IRD system control circuit 220 transmits a deletion request for deleting the specific reservation that has been deleted to the VTR 100, and the VTR system control circuit 20 receives and stores the reservation. Delete the corresponding reservation information from the contents.

In this embodiment, the VTR 100 holds the reservation contents. However, for example, the analog broadcast reservation contents are held by the VTR 100 and the digital broadcast reservation contents are I.
For example, the RD 200 may hold, or all reservation contents may be held by the IRD 200.

In this case, operations such as transmission / reception of reservation information when reservation setting is completed, transmission / reception of reservation information acquisition request when displaying reservation confirmation screen, transmission / reception of deletion request when reservation deletion is performed, etc. Although it will be different from what was demonstrated above, since these can be considered easily, it does not explain in particular.

When the playback button 313 of the remote control 260 is pressed, the VTR system control circuit 20 sets the mechanism such as the signal processing circuit 14 and the rotating drum or capstan to the playback mode, and puts the operation of the VTR 100 into the playback state. At the same time, the analog OSD circuit 15 is instructed to display a “reproduction” character.

The signal reproduced by the magnetic head is reproduced by the video and audio signal processing circuit 14 and output from the analog OSD circuit 15 (video signal only) and the output terminal 16 so that the video and audio being reproduced on the TV 250 can be viewed.

Note that the operation when displaying the menu screen or the reservation screen during reproduction is the same as the operation at the time of stopping as described above.

When the recording button 315 of the remote control 260 is pressed, the VTR system control circuit 20 sets the signal processing circuit 14 and the mechanism such as the rotating drum and the capstan to the recording mode, and puts the operation of the VTR 100 into the recording state. At the same time, the analog OSD circuit 15 is requested to display “record” characters, the channel number being recorded, and the like.

The signal selected by the input selector switch 13 is recorded by a video and audio signal processing circuit, recorded on a magnetic tape by a magnetic head, and an analog OSD circuit 15 (video signal only).
The video and audio output from the output terminal 16 and being recorded on the TV 250 can be viewed.

As described above, the VTR system control circuit 20 does not accept a setting screen display request or a reservation confirmation screen display request from the remote controller 260 during recording. This is to prevent the recorded video signal from becoming a setting screen or a reservation confirmation screen.

Finally, recording by reservation will be described. In this embodiment, since the VTR 100 holds the reservation information, the VTR 100 also executes the reservation.

  First, execution of analog broadcast reservation will be described.

When the reservation start time comes, the VTR system control circuit 20 turns on the power of the VTR 100, connects the input selector switch 13 to the contact A side, tunes the analog broadcast reception tuner 12 to the reserved channel, and then records. To start. Thereby, the reserved analog broadcast program is recorded. When the reservation end time is reached, the recording ends and the power of the VTR 100 is turned off.

  Next, execution of digital broadcast reservation will be described.

When the reservation start time comes, the VTR system control circuit 220 turns on the power of the VTR 100 and the IRD 200, connects the input changeover switch 13 to the contact D side, tunes the IRD 200 to the reserved channel, and starts recording. To do. Thereby, the reserved digital broadcast program is recorded. When the reservation end time is reached, recording is stopped and VTR100 and IRD2 are stopped.
Turn off 00.

In this embodiment, since the VTR 100 holds all reservation contents, VT
R100 is executing the reservation, but conversely, the IRD 200 holds all the reservation contents and the IR
It is also conceivable that D200 performs a reservation. At this time, VTR100 and IRD200
The IRD 200 may perform a series of operations such as starting up the power supply, switching control of the input selector switch 11, tuning of the analog broadcast or digital broadcast receiving tuner, and starting recording of the VTR 100. There are various methods, but these are easily considered and will not be described in particular.

When the VTR 100 cannot communicate with the IRD 200, the VTR system control circuit
20 determines that the IRD 200 is not connected to the communication line 270, returns the operation of the VTR to the conventional operation, and displays the setting screen, the reservation screen, and the like on the analog OSD circuit 15. Similarly, IR
When the D200 cannot communicate with the VTR 100, the IRD system control circuit 220 sets the VTR1.
It is determined that 00 is not connected to the communication line 270, the IRD operation is returned to the conventional operation, and the status display such as the current reception channel number is displayed by the decoder 203.

  The operations of the VTR 100 and the IRD 200 at this time are performed using the respective dedicated remote controllers.

6 and 7 show that when the VTR 100 and the IRD 200 cannot communicate, the IRD 200 and the VTR 100
FIG. 6 shows each setting screen displayed, and the operation for recording the sub-audio of digital broadcasting at a triple speed will be described with reference to FIGS.

First, a method of selecting the IRD sound as the sub sound using the IRD dedicated remote controller will be described.

First, a setting screen selection screen 600 is displayed by pressing a setting screen button. On the screen displayed by IRD200, move the cursor to the item you want to change with the cursor button and press the enter button.
A setting screen for items related to the content is displayed. Here, the shaded area 601 indicates the position of the cursor.

In this case, in order to select an audio signal, the cursor is moved to “video / audio / data selection” and the enter button is pressed to display the video / audio / data setting screen 610. Here, the shaded area 611 indicates the current cursor position, and the shaded areas 612, 613, and 614 indicate the currently set items. In the setting screen 610, since the “main” sound is set as the sound, the cursor is moved to the “secondary” sound and the determination button is pressed to change the setting to the “secondary” sound.
Finally, move the cursor to “End Setting” at the bottom right of the screen and press the Enter button to end the audio setting.

Next, a method for setting the recording tape speed of the VTR to three times using the VTR dedicated remote controller will be described.

First, a setting screen button is pressed to display a setting screen selection screen 700. On the screen displayed by the VTR 100, when a numeric button corresponding to the setting content to be changed is pressed, a setting screen for items related to the content is displayed. Here, the number button “2” is pressed to display the video mode setting screen 710. Here, a hatched portion such as 711 indicates the current setting content. At present, since the recording tape speed is set to “standard”, the number button “5” is pressed to set the recording tape speed to “3 times”. When the numeric button “5” is pressed again, the recording tape speed returns to “standard”. Finally, the setting screen button is pressed to finish the setting.

Finally, by pressing the record button to put the VTR 100 in the recording state, the digital broadcast program can be recorded in the “sub audio, triple mode”.

8 and 9 show a program guide screen displayed by the IRD 200 and a reservation setting screen displayed by the VTR 100 when communication between the VTR 100 and the IRD 200 is not possible. This will be described with reference to FIGS.

First, a method for reserving a desired program by IRD using an IRD dedicated remote controller will be described.

First, the program guide button is pressed to display the program guide screen 800. The program guide screen displays a list of broadcast dates and titles of programs to be broadcast in the near future. On the program guide screen, the cursor is brought to a desired program with the cursor button, and the program is reserved when the enter button is pressed. Here, the shaded area 801 indicates the current cursor position. Screen 800
Then, we are going to reserve news broadcast on channel 171 from 17:00 to 18:30 on Thursday, 27th, and press the enter button here to reserve news, and reception of channel 171 will start at a predetermined time. .

  Next, a method of setting a VTR reservation using a VTR dedicated remote controller will be described.

First, a reservation setting screen 900 is displayed by pressing a reservation setting button. On the reservation setting screen, a channel, recording date, start time, and end time are input with numeric buttons to set a reservation. When “00” is input to the channel, the signal input from the external input terminal of the VTR is selected. A screen 910 shows a screen when the numeric buttons are pressed in the order of “002717001830”, and the content of the reservation is “record the signal of the external input at 17: 00 to 18:30 on the 27th”. When all items are entered and the reservation setting button is pressed, the set reservation is saved and the reservation screen is terminated.

Thus, in order to make a reservation recording of a digital broadcast program, it is necessary to set a reservation for both the IRD and the VTR, and the user notes the broadcast date, start time, and end time of the program reserved by the IRD. Therefore, it is necessary to input such information to the VTR.

As described above, when the VTR 100 and the IRD 200 cannot communicate with each other, the user's operation is very troublesome, but it is possible to record a digital broadcast program in a predetermined mode or to make a reservation recording.

  FIG. 10 is a block diagram showing a second embodiment of the recording / reproducing apparatus according to the present invention.

In this embodiment, the IRD 200 receives an operation request from the remote controller 260, and the IRD 200 and the VTR 100 are received.
This is an example of performing the operation. In the figure, reference numeral 262 denotes a receiving unit of the remote controller, and the remote controller 260.
The user's operation request is transmitted to the IRD system control circuit 220.

The operation in the apparatus of FIG. 10 will be described when the setting screen button 307 of the remote controller 260 is pressed.

When the setting screen button 307 of the remote controller 30 is pressed, the IRD system control circuit 220 detects this, creates a setting screen, and issues a display request to the decoder 203. VTR system control circuit 20 is IRD2
When 00 detects that the setting screen is displayed, the video input selector switch 13V is connected to the contact D side. As a result, the setting screen is displayed on the monitor screen 252.

If the VTR 100 is recording, the VTR system control circuit 20 sends a request to end the setting screen to the IRD 200 so that the video signal being recorded does not appear on the setting screen, and changes the state of the video input selector switch 13V. Leave it as it is.

However, in this method, when a digital broadcast program is recorded, the IRD 200
The setting screen is recorded on the magnetic tape until a setting screen end request is received from R100. Therefore, before the IRD 200 starts displaying the setting screen, it requests that the video output from the VTR 100 be a digital broadcast video and cancels the display when the VTR 100 rejects it, or the IRD system control circuit 220 causes the VTR 100 to Monitor the running state of the V
It is conceivable that the TR 100 may operate so as to cancel the setting screen display request during recording.

Although it is possible to operate using both the VTR100 dedicated remote controller and the IRD200 dedicated remote controller, the contents of the communication and operation of the VTR100 and IRD200 at this time can be easily estimated, and thus will not be described in particular.

  FIG. 11 is a block diagram showing a third embodiment of the recording / reproducing apparatus according to the present invention.

In this example, a video output changeover switch 40V for selecting and outputting a video signal recorded and reproduced by the VTR 100 and a video signal supplied from the IRD 200 is provided immediately before the analog OSD circuit 15.

In this case, the setting screen displayed on the IRD 200 can be output from the VTR 100 by setting the video output changeover switch 40V to the contact D side, so that information can be displayed on the IRD 200 while recording an analog broadcast program. become.

  FIG. 12 is a block diagram showing a fourth embodiment of the recording / reproducing apparatus according to the present invention.

In this example, instead of the decoder 203 used in FIG. 1, in addition to a video signal for displaying information by the digital OSD circuit 2032, a decoder having a function of outputting a video signal for recording that always displays a digital broadcast video. An example using 213 is shown.

FIG. 13 is a block diagram showing the internal components of the decoder 213. The decoder 213 in FIG.
3 adds one small encoder 2032 to the decoder 203 in FIG. 3 and directly supplies the digital signal output from the expansion circuit 2031 to the added encoder 2033. This makes digital OSD
Since the video signal that does not pass through the circuit 2032 is not displayed with information such as a setting screen, it can be used for recording.

Also, the VTR 100 is provided with a terminal for inputting two types of video signals output from the IRD 200, and the video signal for recording is supplied to the video input terminal 10V connected to the input selector switch 13 and newly provided. A video signal for displaying information such as a setting screen is supplied to the video input terminal 50.

In this case, by setting the video output changeover switch 40V to the contact D side, it is possible to display information such as a setting screen displayed by the IRD 200 during recording of digital broadcasting in addition to recording of analog broadcasting.

  FIG. 14 is a block diagram showing a fifth embodiment of the recording / reproducing apparatus according to the present invention.

In this example, the VTR 100 is a recording / reproducing apparatus that selects, records, and reproduces one of analog video and audio signals and digital information signals.

When recording a digital information signal, the VTR system control circuit 20 connects the input switch 13 to the contact D side and the digital signal input switch 230 to the contact R side.

The digital information signal received by the digital broadcast receiving tuner 202 is output from the digital signal output terminal 231, input to the VTR 100 from the digital input terminal 50, recorded by the digital signal processing circuit 51, and recorded on the magnetic tape by the magnetic head. To be recorded. At the same time, the digital information signal is converted into an analog video and audio signal by the decoder 203 and output from the output terminal 204. The video and audio signals of this digital broadcast are input to the VTR from the input terminal 10, output from the output terminal 16 via the input switch 13, the signal processing circuit 14, and the analog OSD circuit 15 (video signal only) and supplied to the TV 300. The Thereby, the video and audio of the program digitally recorded on the TV 300 can be viewed.

At this time, since the digital information signal output from the digital output terminal 231 by the IRD 200 is a signal before the information signal is added by the digital OSD circuit 2032, the digital information recorded digitally even if the information is displayed on the digital OSD circuit 2032 It has no effect on the signal. Therefore, information can be displayed by the IRD 200 during digital recording without providing a video output switch as in the third and fourth embodiments.

When reproducing digital information signals, the VTR system control circuit 20 has an input selector switch.
13 is connected to the contact D side, and the digital signal input selector switch 230 is connected to the contact P side.

Then, the digital information signal reproduced by the magnetic head is reproduced by the digital signal processing circuit 51 and output from the digital output terminal 52, and input from the digital input terminal 232 to the IRD 200. The digital signal input signal changeover switch 230 and the decoder 203 are connected. And output from the output terminal 204 as analog video and audio signals. These signals are input again to the VTR 100 and supplied to the TV 300 through the same path as that used during digital recording. As a result, the video and audio being digitally played can be viewed.

The operation when recording or reproducing an analog signal is the same as the operation of the apparatus of FIG.

  FIG. 15 is a block diagram showing a sixth embodiment of the recording / reproducing apparatus according to the present invention.

In this example, the VTR 100 and the IRD 200 are not separated, but an integrated recording / reproducing apparatus. In this case, an input / output terminal for each signal going back and forth between the VTR 100 and the IRD 200 becomes unnecessary.

Also, since the IRD 200 knows in advance the types and names of the setting items held by the VTR 100, their choices and their names, a VTR setting screen can be created by acquiring only the current state of those setting items. .

1, 10, 11, 12, 14, and 15, VTR 100 and I
Although the operation of the RD 200 is performed using the remote controller, this can also be performed using the operation buttons arranged on the main body of the VTR 100 or the IRD 200. Further, although the means for outputting the status of the VTR 100 and the IRD 200 as information is based on the screen using the OSD circuit, it may be considered to output the information by voice.
